Diablo 3 has sold over 20 million copies since it launched in 2012

Since Diablo 3 launched back in 2012, the game has sold over 20 million copies as of June 30, 2014. The news comes from Activision-Blizzard's second quarter earnings call, where the company released a press release announcing the milestone.

The 20 million copies includes expansions and digital sales, as well as the usual brick-and-mortar retail sales. At the end of 2013, Diablo 3 had sold 15 million copies, which means Activision-Blizzard have sold five million copies since the beginning of the year, and are sitting on an average of five million copies sold every six months or so.
